Deploy problem with QtQuick.Controls 2.0

[Galbarad]

Hi all
In case you remember my previous posts ;) you know than I add qml form with QtQuick.Controls 2.0 into my project
when I run project in QtCreator all fine, but when I run app from application folder start problem
project running and main form appears, but when I try open form with QtQuick.Controls 2.0 they do not show
looks like missing some dll (but without QtQuick.Controls 2.0 all work fine because I already copy all needed dlls into "user application folder")
so maybe somebody know missed dll

import QtQuick.Controls 2.0

also I try to use with windeployqt following keys but with same result (main form appear, Control2 form no)

d:\Qt\5.7\msvc2013_64\bin\windeployqt.exe --release --dir d:\SVN\PROJECT\Qt\OracleDeploymentTool\release\x64_test --qmldir d:\Qt\5.7\msvc2013_64\qml d:\Dropbox\Work\Qt\build-OracleDeploymentTool-Desktop_Qt_5_7_0_MSVC2013_64bit-Release\release\OracleDeploymentTool.exe

thanks for help

I had a similar problem. Manually copying these libraries helped me:

• Qt5QuickParticles.dll (because I used particles)
• Qt5QuickControls2.dll
• Qt5QuickTemplates2.dll

Maybe that will help you too?

Regarding windeployqt - I gave up on it, for me it's easier to copy libraries myself.

hi @veryqtperson thank you for answer
yes I try add this dlls but looks like its not enough
maybe I should start copy dlls from bin one by one?((

[veryqtperson]

Well, that's what I usually do.
But I start with copying all the libraries and then delete one by one to find out which are really needed :)
After some time you will know better which libraries are required for which type of application, so it gets easier.

ok, thank you @veryqtperson
I'll try

[Galbarad]

I add all dll from bin to my release folder without result, so I do what I must to do long time ago
I add alert dialog and rise it with qml error )))
so I get error message "qtquick.controls version 2.0 is not installed"

[veryqtperson]

Do you have QT += qml quick in your .pro file?
And maybe import QtQuick 2.7 before import QtQuick.Controls 2.0 (I don't know if it's relevant)?

@Galbarad , thanks for the sample folders layout - it helped me to partially resolve the similar issue with missing QtQuick.Layouts (like "module "QtQuick.Layouts" is not installed").
However doing this manually is too tedious, so I'd vote for windeployqt.exe which does its job (in Qt5.15.5) quite good (especially after you limit the copied modules with the options).
